Want Better Results From Your Marketing? Use Our Process for Iteration

Great marketing isn’t lucky. 

It’s the product of a strategy that guarantees great results.

Yet, many businesses still treat marketing like a one-shot effort: launching the campaign, crossing their fingers, and moving on. 

The results? Inconsistent, at best.

Iteration changes that.

It replaces hope with a structured process for testing ideas, learning from results, and applying those lessons to improve key metrics like conversion rate, customer retention, and ROI.

In this guide, you’ll learn a framework to help you run smarter campaigns that are consistently optimized based on data and customer behavior.

What is the Iteration Process?

The first thing that comes to mind when most marketers hear “iteration” is A/B testing for email subject lines. 

But what we’re talking about in this guide is more than occasional tweaks. It’s a built-in system for improvement that’s applied consistently to assets, offers, and messaging.

This is an approach that pays off. 

When you move from reactive adjustments to a proactive system of testing and refinement, you reduce wasted spend, increase campaign ROI, and improve customer engagement over time.

Why?

A strong iteration process creates a feedback loop that can be used to consistently improve your marketing. 

Three Inputs That Power Iterative Marketing

The process begins with input. 

This is how you learn what campaign aspects are effective and what needs to change. 

There are three that matter most.

1. Data: Numbers That Drive Decisions

Numbers reveal what’s happening. 

Whether you’re tracking email open rates, click-through rates, conversion rates, or ROAS, your first job is to measure performance against your goal.

This tells you which tactics are pulling their weight and which are underperforming.

Key metrics to measure can include:

• Click-Through Rates (CTR): Measure user engagement with your emails, ads, and content.
• Conversion Rates: Track how many users take desired actions, like signing up or making a purchase.
• Customer Lifetime Value (LTV): Understand the long-term value of each customer.
• Return on Ad Spend (ROAS): Calculate the revenue you earn for every dollar spent.

2. Customer Feedback: Direct Insights from Real People

While data shows results, feedback explains them. 

Customer feedback is your direct line to audience preferences and pain points. It tells you not just what users do, but why they do it. 

Collect feedback through surveys, community forums, product reviews, social media comments, and customer support interactions. 

Whether customers love your product, struggle with your website, or have specific complaints, this feedback gives you the context behind your metrics.

It helps you fine-tune your messaging, address customer concerns, and create experiences that resonate.

3. User Behaviour: Actions That Reveal Intent

User behaviour data shows how people actually engage with your marketing. 

It goes beyond what users say to reveal what they actually do. By observing user actions, you gain clear insights into which elements of your marketing are effective and which need improvement.

Tracking user behaviour helps you identify what captures attention, what drives clicks, and where users lose interest. 

Tools like heat maps, click tracking, and usability testing provide a clear picture of how users navigate your website, interact with landing pages, and respond to your content.

This data is your best tool for optimizing website and landing page layouts, refining calls to action, and creating user experiences that drive conversions.

The 5-Step Framework for Effective Iteration

With the right inputs in place, the question then becomes: How do you act on them systematically? 

That’s where this five-step framework comes in.

To run a campaign that improves over time, you need a process that goes beyond “test and hope.” 

Here’s how to make that process reliable.

Step 1: Set Your Goals

Every successful iteration process begins with planning. 

Decide what you are optimizing for. Make your objectives specific, measurable, achievable, relevant, and time-bound (SMART).

For example, imagine a scenario in which you’re sending an email campaign for a direct to consumer eCommerce store. Your first step might look like this:

• Goal: Increase email conversion rate by 10% within 30 days.
• Primary KPI: Conversion rate (purchases from emails).
• Secondary KPIs: Click-through rate (CTR), open rate, landing page bounce rates
• Iteration Considerations: Optimized subject lines, CTA buttons in the email, landing page CTA buttons.

By setting clear, measurable goals, you ensure that your iteration process has a clear direction, making the testing and optimization efforts to come far more effective.

Step 2: Design Test-Ready Assets

Most teams treat testing as something that happens after a campaign is launched. 

But this can slow things down.

Instead, build modular assets from the start. Design emails, ads, landing pages with testing in mind, so that elements (headline, CTA, images, body copy) can be easily swapped without needing a complete redesign.

This also requires each asset being integrated with tracking tools, so you can monitor performance accurately.

Asset List Example

• 2 subject lines for an email
• 2 email CTA options
• 2 headline options for a landing page
• Video vs. static options
• 2-4 static options for an ad

Pro Tip: Use a version control system to track different variations and their performance. Make sure to properly name each test.

Step 3: Test Strategically

Once your assets are designed with testing in mind, it’s time to put them into play.

Testing isn't just about running experiments. It's about running the right experiment, for the right reason, with the right setup. 

Here’s how to approach it step by step:

I. Develop Your Hypothesis

Every test should start with a clear, testable idea rooted in your original campaign goal.

For example: Personalized subject lines will increase open rates among returning customers.

This keeps your tests focused and ensures that your insights are actionable.

II. Choose the Right Type of Test

Not all tests are created equal—and neither are all testing situations.

Choose your method based on what you’re trying to learn, the available traffic, and the audience segments involved.

Here are three core formats—beyond the standard A/B Testing—to consider:

• Segmented Testing: Ideal when you want to compare performance across different audience types—like new vs. returning users, or high-value vs. low-value customers.
• Sequential Testing: Best for measuring impact over time. Use this to track user behavior before and after a change, especially for trend-driven or seasonal campaigns.
• Multivariate Testing: Use when you want to test combinations of variables (like headline, image, and CTA) simultaneously to identify the highest-performing setup.

The method you choose will determine what kind of asset variation and traffic volume you'll need—so plan accordingly.

III. Set a Clear Testing Window

Establish a fixed duration—typically between 7 and 14 days—or run the test until you reach statistical significance. Avoid cutting tests short or letting them run indefinitely.

IV. Monitor in Real Time

Use tools like Google Optimize, VWO, or Hotjar to track performance and observe user behavior as your test runs. 

This can help you catch unexpected friction points or early signs of a winner.

Pro Tip: Maintain a centralized log of every test—include your hypothesis, test type, asset variations, performance data, and final insights. Over time, this becomes a playbook for what works (and what doesn’t) in your marketing.

Step 4: Use the 3L Method

Running a test is only valuable if you learn from it—and apply what you learn. 

To keep things simple and consistent, use the 3L Method to break down your results:

• Learn: Identify which variation performed best, and dig into why. Look for behavioral patterns or shifts in your key metrics.
• Leverage: Apply what worked to your next campaign. Let strong results guide your new baseline.
• List Next Steps: Document what you’ve learned and outline your next test. Keep your momentum going by building on proven wins.

This type of analysis could look like this:

• Tested Asset: Email Campaign
• Winning Variation: Email with direct, action-oriented CTA ("Shop Now") outperformed a passive CTA ("Learn More").
• Key Learning: Direct, action-focused language drives higher conversions.
• Next Steps: Use direct CTAs across all email campaigns.

Pro Tip: Don’t get lost in the weeds and overanalyze everything. Focus on insights you can act on. A simple dashboard or spreadsheet with core metrics is more useful than a dozen fragmented reports.

Step 5: Optimize and Repeat

Optimization is a continuous process, not a one-time event. Your goal is to build a system where testing and improving become standard practice, not special projects.

Here’s how to keep that system running:

Apply What Works

Update your live campaigns with the winning variations you’ve identified. Build on what’s proven to perform.

Automate Future Testing

Use tools like Google Optimize or Convert to run ongoing tests with minimal manual effort. Let the system do the heavy lifting.

Schedule Regular Reviews

Set recurring checkpoints—monthly, quarterly, or campaign-based—to revisit each asset and ask: Is this still the best version we can run?

What Continuous Optimization Looks Like

For a landing page, this might mean:

• Updating the headline monthly to reflect new insights.
• Testing new product images every quarter.
• Experimenting with different CTA placements to maximize conversions.

Your Next Step: Build, Test, Improve, Repeat

You don’t need more ideas. You need a system to make your ideas better.

That’s essentially what this iteration process we outline above delivers. 

It helps you:

• Set clear, measurable goals.
• Build assets designed to adapt.
• Run tests that reveal what actually works.
• Apply real insights to drive better outcomes.
• Repeat the cycle—faster, smarter, and more confidently each time.

This isn’t about chasing perfection. It’s about creating momentum. And driving results.

Every test gives you a clearer picture. Every improvement compounds. And over time, what used to feel uncertain becomes predictable—and scalable.

So pick a campaign. Set a goal. And launch the first test.

Then take what you learn and make the next version better.

Not eventually. Right now.
